| Abstract: | An analysis of spectral characteristics of SPOT5 images was conducted and compared with same categories,spectral characteristics of images obtained by common fusion methods was described;the advantage and disadvantage of the methods also have been compared.On basis of algorithm of BROVEY,an experiment on fusion of false colors of SPOT5 images was carried out.Then the characteristics of fundamental algorithms and image effects were explained.Aim at the inadequate of vegetation cover strata and blue hilly terrains shadows,two algorithms of fusion for improvement are introduced.The principles of algorithms were interpreted and an objective analysis of the images characteristics obtained after fusion also has been given. |
